IMPROVED SUGAR-EVAPORATOB.

IS ALL WHOM IT MAY CONCERN;

Be it known that I, WILLIAM 0. SMITH, of Warrensburg, in the county of Johnson, and the State of Mis souri, have invented a new and improved Sugar-Evaporator; and that the following description, taken in connection with the accompanying drawings hereinafter referred to, forms a full and exact specification of the same, wherein I have set forth the nature and principles of my said improvementaby which my invention may be distinguished from all others of a similar class, tog'ether'with such parts as I claim, and desire to have secured" to me by Letters Patent.

This invention relates'to a new and improved sugar-evaporator, designed, more especially, for the application of a new chemical clarifying process, and evaporating the juice of the sorghum and other sugar-canes, and to admit of the work being accomplished in a perfect manner by persons of ordinary ability.

In the accompanying sheet of drawings---- 7 Figure 1 is a perspective view of my invention in a portable form, which may be mounted upon wheels or legs. I

Figure is a. perspective view of the interior, with the fire, front, pans, and chimney removed; of the furnace in a stationary form, composed of brick-masonry.

Figure 3 is a view of the ash-pit, S, disconnected from the main body, fig. 1.

Figure 4 is an interior view of the construction of the damper Gr, disconnected from the main body.

Similar letters of reference indicate corresponding parts.

- It represents the body of the device, which may be constructed either of sheet-iron or cast-iron plates, for portable apparatus, and of brick or stone-masonry for stationary purposes, andis mounted by two main pans, the clarifying-pan A A, divided into two compartments by the partition (2.

l The bottom and back of the pan A A should be made of sheet copper. The front, ends, and partition may be composed of wood, and the evaporating-pan, B B, is divided into two compartments by the partition 7', connected by the gate h, the pan A A being elevated above the panB B, so thatits contents will flow, when desired, into the lower pan. The door H communicates with the fire-chamber, the grate of which is shown'in fig. 2, indicated by the letter z.

I S is the ash-pit; O is the door which communicates with it, and operated by the crank, 0. The bottom of tho ash-pit is composed of bars of iron, pivoted to two cross-bars, s s, which are also pivoted at 70 k, and furnished with a handle, K, as is represented in fig 3, the object of which is to catch the small coals as they fall through the upper grate, which supports the fuel, and thereby utilize a large portion which would be otherwise lost, and also to prevent the effects of.a strong wind when operated in the open air. By shaking the handle K from side to side, the ashes will fall through, whilethe coals will be retained.

In fig. 4, g g g g g is a series of dampers, connected by cranks to the bar G, moving of which to the left brings the damper from a pendent to a horizontal position, to checlnwhen desired, the boiling of the finishing" end of the pan B, and will be readily understood by reference'to the drawings.

The space beneath the pan A A is divided into two lines by the partition D, composedof a cast-iron plate. At the mouth of the dues are the dampers m m, worked simultaneously by the crank M, so that by opening one the other is closed, thus alternately heating the contents of eithercompartment of the pan.

Upon each side of the pan B, which is composed of cast iron, is a row of cogs, one row of which is seen at L, on which is mounted a movable frame, F, carried by two small cog-wheels, one of which is seen at c, and is kept in position by its heads, N N, composed of cast iron, having flanges, which engage 'the under side of the bars containing the cogs, and through which runs the shaft, to which are secured the cog-wheels, and having attached at the rear askimmer, 6, represented as being broken off at one end. In front is attached a driver, J, having a handle, 6, by means ofhinges, and can be raised from the bottom of the pan, when desired, by turning the cranks n n. The frame, with its attachments, is moved in either direction lengthwise of the pan.

In operating the abovc described invention, the pans A A are filled with juice containing the defecating agent, and' also a suflicient quantity in the lower pan' to prevent burning. Adjust the dampers m at so as to turn theheat all under one compartment of the pan A A. When its contents are brought to .the desired temperature, turn the heat under the-other end Now the defecated juice may be neutralized, settled; or otherwise treated, and drawn ofiinto the evaporating-pan B B, the flow being regulated by the faucet, u, to correspond with the loss caused'by evaporation. The flow can also be adjusted between the compartments of the pan B B, by the gate 71, so that either of the compartments of the pan A A may be emptied and the sediment removed; and be refilled at the time the other has arrived at the proper temperature; P P are spouts, for drawing out the water used in rinsing the pans. i

As the contents of the compartment B, in front of the driver J, become less by evaporation, they are kept at the desired depth by an occasional movement of the crank n, thus driving the siruptcw'ard the finishing-end of the pan, which,-when finished, can be instantly discharged at the spout Y, and conducted by a pipe to the cooler; then raise the driver J,.and move it back to the other .end, the skimmer carrying ,the' scum before 'it, thus facilitating the work without danger of scorching the sirnp.

I do not claim, in suga'r-evaporators, the employment or use of a series of pans, arranged at difl'erent heights; neither do I claim a partition with a gate, -no'r apartition that can be moved or placedat difi'eren't points in the "pan, for theyhave been previously used; but

I do claim as new, and desire to secure by Letters lfateht-f- The pan A A, as arranged on the body R of the device; an'd used in connection; with the flues formed bythe partition D and the dampers m m, and the pan B B,'divided by the partition r, having'a gate, 7:, when used in connection with the movable frame F, carrying the skimmer 2', and a driver, J,-moving upon thecogs L, by means of the cog-wheels c, operated 'by' the cranks n n, and used substantially as described, and for the purposes set forth. V p v v I further claim thedam-pers g g g g, with the connecting-bar G and the ash-pit S, when applied to a sugarevaparator, substantially as and for the purpose specified.-
